Its all about personal preference. Here is what I would choose:

Ducks - full with #2 or #4 steel shot, with lead #4 modifed or full. Bismuth or Tungsten, check with manufacturer. Alot of this is going to depend upon how you hunt, the weather and the distance you normally shoot.

Turkey - full but I haven't done much turkey

Doves - full flight, #6 or #7 1/2 or #8 lead, modified. Alot depends if windy or you are expecting to jump them.

Grouse - Imp cylinder #6 or #7 1/2 lead if you have fast reactions or hunting behind a pointing dog. Modified #6 lead if you like to make sure shots, ie. line up barrel.
